Our QA Series air only units are available in standard sizes from 1,000 to 100,000 CFM. 

Standard units are manufactured with heavy gauge G90 galvanized steel, insulated where needed with 2" 3lb., non-wicking insulation lined with 20 gauge galvanneal to eliminate air borne fibers from entering the air stream. 

Fans are AMCA rated, either forward curve or backward inclined. 

Air only units are primarily used to provide positive air flow and equalize building temperature.
